That's what I was thinking. No adjustments were made between the dyno and installing in the truck, so I'm really surprised and frustrated to have this issue. They did mention something about it having trouble idling at the dyno, but we were able to break it in and pull several runs. They didn't mention it idling really rich after they adjusted it to idle and on my best run the AFR readings from 3,944 to 6,010 rpms show a min of 12.87 and max of 13.39.
For fuel I have a mechanical Edelbedrock fuel pump. 110gph regulated at ~5.5-6psi through 3/8 fuel line.
